GASKET-LINING APPARATUS.

Application filed November To all whom it may concern:

Be it known that I, ARTHUR C. MAYER, a citizen of the United States,residing in Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Improvement in Gasket-Lining Apparatus,of which the following is a specification.

This invention relates in general to apparatus for forming and-applyinggaskets to the flanges of can ends, and has more specilic reference tomeans for preventing the feeding of can ends to be lined into theapparatus in the absence of a gasket in posi- ,tion to be applied.

In the operation of machines of this charf acter it sometimes happens,either because of imperfect operation of the feeding mechat nism orimperfect functioning of the cutting i devices, that a gasket is notpp gnt in the {turret at the point from which it should be applied to a canend, and in this event it is desirable to prevent the feeding of an end,since it must necessarily pass out of the ma- Fliiiibuiiliiet i it is aprincipal object of the present ini vent-ion to provide means controlledby the 5 presence or absence of a gasket at a certain 5' station in theapparatus for rendering ineffective the operation of the can end feedingmechanism unless am is ready to be 1 applied to an end, the mechanismwhich I have provided being descriptively termed a no gasket, no enddevice.

A. further object of the invention is the provision of mechanism foraccomplishing the foregoing object which in no way interferes with thenormal operation of the machine, and which is entirelynutomat ic inaction.

Another object of the invention is the provision in apparatus of thischaracter of means for restoring the operative condition of the feedingmechanism simply by the nornial operation thereof after correction ofthe condition which caused the stoppage.

Still another object of the invention is the provision of a relativelysimple mechanical structure adapted to obstruct the operation of thefeeding mechanism in the event mentioned, "-d a sensitive electricalcontrol for said structure with precision and certainty in everyinstance of failure to provide a gasket at a predetermined point.

Numerous other objects and advantages of the invention will be apparentas it is 13Gb. ter understood from the following description, which,taken in connection with the accompanying drawings, discloses apreferred embodiment thereof.

Referring to the drawings,

Figure 1 is a front elevation of a machine embodying the principles ofmy invention;

Fig. 2 is a greatly enlarged plan view of a portion of the apparatus,taken substantially on the line 22 of Fig. 1;

Fig. 3 is a vertical section taken substantially on the line 33 in Fig.2, certain of the parts being broken away for convenience ofillustration;

Fig. 4 is an enlarged fragmentary view of a portion of the rear end ofthe machine, certain parts being shown in section; and

Fig. 5 is a horizontal section taken substantially on the line 55 ofFig. l.

The general organization of the apparatus in which my invention isembodied, in the present instance, may be observed by reference to Fig.1, which requires only a general description since the greater part ofthe mechanism there shown is not concerned with this invention and isfully shown and described in an application heretofore filed by MagnusE. lVidell and lVarren A. Smith, bearing Serial No. 448,625.

The function of the structure of this machine is to form gaskets fromblanks fed thereto and to apply the same to the flanges of can ends fedinto the machine at a station beyond that at which the formativeoperation upon the gasket blanks takes place. To this end a turret 11 isprovided in a frame 12 supported upon a base 13, and extending outwardlyfrom the frame on the plane of the turret are supports 14: and 15) forthe gasket blank and can end feeding mechanisms respectively.Stackholders 16 for the gasket blanks are provided above the support M,and feeding mechanism, not shown in detail, is employed to individuallyfeed the blanks into ports 17 spaced about the periphery of the turret.The feeding of these blanks, as well as that of the can ends, which isdone by means to be loo hereinafter described, and the variousoperations of forming and applying the gasket liners are accomplished bypower introduced into the apparatus through a pulley 18 which is carriedon a drive shaft 19 journaled in upper projections 21 and 22 of theframe 12. The pulley 18 is loose upon the shaft 19 and adapted to beoperatively connected therewith by a clutch 23 operable by a hand lever24E through a connecting rod 25 rotatably secured in the upperprojection 22, and ca 'rying a depending fork 26 having connection withsaid clutch. A hand wheel 27 is provided for manual operation, and theparts just described are assembled nnder the pressure of a coil spring28 on the end of the shaft 19. Said shaft carries a bevel gear 29meshing with a bevel gear 81 secured on a vertical shaft 32, which atits lower end is provided with a pinion meshing with a gear 31 securedon a shaft 35 which has also secured thereto an arm 36 carrying a roll37 adapted to drive the slotted wheel 38 with a Geneva stop movement.The wheel 38 is fixedly secured to a shaft 39 having bearings at 11 inthe frame 12 and being operatively connected at its upper end with theturret 11. Through this mechanism an intermittent motion is imparted tosaid turret to permit performance of the various operations of themachine at predetermined stations. The shaft 32 has secured thereto justabove its bearing -12 abevel gear 43 adapted to drive a combined beveland spur gear 44 secured upon a transverse shaft having bearings in themain frame and having at its opposite end a crank disk &5, havingsecured thereto a crank pin 46 held in a wrist 17 and connected by alink 18 and a universal oint 19 with an arm 51 rigidly secured at oneend to a shaft which is rigid with an arm 52 adjustably secured at 53with the blank feeding mechanism heretofore referred to.

The blanks which are fed by the mechanism just described into the portsof the turret 11 are seated by a seating die 54ccarried by a rod 55periodically recharocated by means of a bell crank lever 56 pivoted at56 and carrying on its upper arm a roll 57 following the groove 58 of anoffset cam member 59.

Subsequent rotation of the turret brings the blank to a station where ithas the core removed therefrom by die members operated through theinstrumentality of crosshea-ds 01 and 62 carried respectively on thelower and upper transverse shafts. The next step in the rotation of theturret brings the gasket, indicated in Figs. 2 and a by the referencenumeral 03, to an idle station. which is the one immediately precedingthe lining station at which a can end is fed into the machine bymechanism to be now described.

Stackholders 612 are provided above the support 15 for holding a supplyof can ends which are individually separated and fed into the turret bya feeding slide 65. The stack extends through a guide 66 connected bypivots 67 and ($8 with toggle arms 69 and 71 and beveled stack lifters70 and 70 respectively. The arms 69 and 71 are joint ed and carryrollers 72 and 73, their rear extensions being secured together by aspring 7 1 secured in notches 7 5 and 7 G. The slide (35 is beveled at7'7 and is reciprocated by means of an arm 78 connected by a connectingrod 79 with a lower extension 81 of the arm 52. hen this slide is movedout wardly, permitting the rollers 72 and 73 to ride down the beveledfaces 77 the spring 74 draws the rear extensions of the arms (59 and 71together causing the stack lifters 7 O and 7 0 to move inwardly asuliicient distance to raise all but they lowermost end which is thuscut out and fed into the turret upon the subsequent inward movement ofsaidslide.

T have provided means to prevent operation of the end feeding mechanismjust described in the event that a gasket is not po sitioned in theturret so as to be applied to such end in the normal timed operation ofthe different parts. This mechanism coniprises an arm 82 having at itsouter end a finger 83 and normally held at a distance above the arms 69and 71 by a slidable support 8t and a latch member 85 engaging a pin 86extending through the upper part of said member 84-. The arm 82 isfreely pivoted at 87 and is sustained in its elevated position merely bythe support 8 1. Secured to the arms 69 and 71 are inwardly project inglugs 88 and 89 adapted to engage the finger 83 when the arm 82 drops toits lower or operative position. To effect such movement of the arm 82 Iprovide a magnet 91 held by a rod 92 secured in a casing 93 by means ofnuts 9% and 95. This magnet is positioned near the latch 85 and whenenergized draws said latch from beneath the pin 86, allowing the support84 to drop, which in turn permits the finger 83 to be carried betweenthe lugs 88 and 89 to prevent operation of the feeding device toseparate a can end from a stack.

To energize the magnet 91 an electric circuit is provided comprising awire 96 con nected by a post 97 with a wire 98 which is secured to apost 99 in an insulated contact member 101, extending into a groove 102extending about the under side of the turret 11. A contact pin 103extends downwardly from a horizontally positioned rod 101 secured in avertically extending rod 105 adjustably secured in an arm 106 which isslidable on another vertical rod 107 and adapted to be raised andlowered through the in strumentality of a die mounting 111 carrying thedie which operates upon the blank at the next preceding station. Thecurrent is transmitted from the contact pin 103 through the machine andthrough a wire 112 secured to the machine by a binding post 113 to abattery or generator (not shown) which is also connected with the'magnet 91 by a wire 113 through a binding post 11 1 and a wire 115. Thecontact member 101, as has heretofore been stated, extends into thegroove 102 and is of such height as to reach practically the level atwhich the gasket 63 is supported on a ledge 110, being insulated fromthe machine by a fibre plate 117.

When the pin 103 is moved downwardly into the port 17 it forms a contactwith the member 101 if no gasket be present to insulate it therefrom.Upon establishment of such contact the magnet 91 is energized and thelatch 85 withdrawn from its supporting position. Upon breaking of thiscontact the magnet is deenergized and the latch 85 free to be restoredto its supporting position. This is accomplished by means of a spring118 secured in the magnet casing 03 and bearing upon the lower beveledbearing part 119 by which the latch 85 is pivotally secured to a pin121.

The arm 78 is connected with a rod 122 by-means of a sleeve 123 and apin 12a and is reciprocated by the feeding mechanism which actuates saidarm 78. Upon upward movement of the rod 122, a screw 125 which extendsupwardly from a link 126 comes into contact with the lower end of thesupport 8st and elevates it to position to permit engagement of ashoulder 127 of the latch 85 by the pin 86, the under side of thisshoulder being beveled to permit upward move ment of said pin 80. Thelower end of the arm 78 carries a roller 128 which rides in the groove129 of a cam member 131 carried on the outer end of a shaft 132 whichhas hearings in the frame 12 and is rotated by a pinion 133 mes-hingwith the gear 14:, this cam being provided to control the movement ofthe arm 78 whereby the restorative action just described isaccomplished.

If a gasket be present at the detecting station, normal operation of theend feeding mechanism places an end in the turret beneath one of theports 17 and the gasket is seated thereon at the next station by anupper seating die 131 and 135, these dies being operated throughsuitable connections by cams 136 and 13? carried respectively upon theupper and lower transverse shafts. An ejecting rod 138 secured in an arm139 and actuated by the upper seating die operating mechanism isprovided to knock out the lined can ends which fall into a suitableholder or conveyer.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and

it will be apparent that various changes may be made in the form,construction and arrangement of the parts without departing from thespirit and scope of the invention or sacrificing all of its materialadvantages, the form hereinbefore described being merely a preferredembodiment thereof.
